I know you're saying nothing changed, but I'm telling you:

openssl s_client -connect hostname:25 -starttls smtp

Failed with the above error "before" and connects as expected "after" the 
changes outlined.

Thank you for highlighting the accidental allow of 1.0.   That was not 
expected.  The config lines actually came from the Postfix docs, so perhaps 
you'd like to update the docs with saner examples ?  :)
